THE INFLUENCE OF FIELD ASSESSMENT ON THE ACOUSTIC PERFORMANCE OF DOUBLE-SKIN FACADES

摘要: This study assesses and validates the influence of measuring noise levels in the urban environment, site parameters, and glass façade components in responsively reducing sound transmission to the indoor environment. Among the most reported issues affecting workspaces, increased awareness to minimize noise led designers to reconsider the design of building envelopes and its site environment. Outdoor sound conditions, such as traffic noise, challenge building designers to accurately estimate the capability of glass façades in acquiring an appropriate indoor sound quality. Indicating the density of the urban environment, fieldtests acquired existing sound levels in areas of high employment and traffic activity, establishing a baseline for sound levels common in urban areas. In this study, the city of Los Angeles is used to assess existing soundscapes common in urban areas. Field-measurements for sound transmission loss can establish a baseline performance in a context for sound levels common in urban areas. INSUL is a sound insulation software utilized as an informative tool correlating glass façade parameters with outdoor sound levels based on ISO 717 to predict indoor sound levels. Composed from the sound transmission loss of glass facades simulated through INSUL, results are utilized as an informative tool correlating glass façade components to respond to outdoor sound levels of a project site, achieving desired indoor sound levels based on occupancy. Field-measured sites in Los Angeles indicate the density and activity of the area and responds to the need in emphasizing the influence of site parameters in order to respond …
